I have had the same experience with a 2014 FX4 Ecoboost with the 4.10 Electronic locking differential option. Nearing my first 1,000 miles and I am exactly at 13 MPG for mostly surface street driving and a little freeway driving.
Does it get any better with a few thousand more break in miles or is this reality?

Yep Mileage seems to suck while they are breaking in. new 14XLT,3.55/5.0 /not towing anything yet . Looked at avg yesterday 12.1 for the first 1000miles. My 12 XLT/5.0 took awhile to break in also. give it a couple thousand miles & see what happens but as someone posted 4.10 gears won't help mileage and neither will winter gas.

Excerpted from the 2014 F-150 owner's manual .....
Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles (1600 kilometers) of driving (this is your engine’s break-in period); a more accurate measurement is obtained after 2000 miles - 3000 miles (3200 kilometers - 4800 kilometers)......

Here' my 2014 5.0. And that 19.2 average is also what the computer shows.

NOPE! All my friends with that motor suck fuel like a thirsty Hog in a lake, your doomed with that engine it was all hype for fuel economy. But it is by far the BEST motor for duty work, just live with it... And for the record I have 17 friends (personal friends I know) that have the 3.5 ecoboost and they will ALL testify it is a HOG!
